GENERAL SAFETY

RULES

WARNING! Read all instructions

Failure to follow all instructions listed below
may result in electric shock, fire and/or
serious injury. The term “power tool” in all
of the warnings listed below refers to your
main operated (corded) power tool and
battery operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work Area Safety

1) Keep work area clean and well lit.
Cluttered or dark areas invite acci-

dents.

2) Do not operate power tools in ex-

plosive atmospheres, such as in
the presence of flammable liq­uids, gases or dust.

Power tools create sparks which

may ignite the dust or fumes.

3)

Keep children and bystanders
away while operating a power tool.

Distractions can cause you to lose

control.

Electrical Safety

1)

Power tool plugs must match the
outlet. Never modify the plug in any
way. Do not use any adapter plugs
with earthed (grounded) power tools.

Unmodified plugs and matching out­lets will reduce risk of electric shock.

2)

Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators.

There is an increased risk of elec-

tric shock if your body is earthed or
grounded.

3) Do not expose power tools to

rain or wet conditions.

Water entering a power tool will in-

crease the risk of electric shock.

4) Do not abuse the cord. Never use

the cord for carrying, pulling or
unplugging the power tool. Keep
cord away from heat, oil, sharp
edges or moving parts.

Damaged or entangled cords in-

crease the risk of electric shock.

5)

When operating a power tool out­doors, use an extension cord suit-

able for outdoor use.

Use of a cord suitable for outdoor use
reduces the risk of electric shock.

Personal Safety

1) Stay alert, watch what you are

doing and use common sense
when operating a power tool. Do
not use a power tool while you
are tired or under the influence of
drugs, alcohol or medication.

A moment of inattention while oper-

ating power tools may result in per-
sonal injury.

2) Use safety equipment. Always

wear eye protection.

Safety equipment such as dust

mask, non-skid safety shoes, hard
hat, or hearing protection used for
appropriate conditions will reduce
personal injuries.

3) Avoid accidental starting. Ensure

the switch is in the off position
before plugging in.

Carrying power tools with your fin-

ger on the switch or plugging in the
power tools that have the switch on
invites accidents.

4)

Remove any adjusting key or wrench
before turning the power tool on.

A wrench or a key left attached to a

rotating part of the power tool may
result in personal injury.

5) Do not overreach. Keep proper

footing and balance at all times.

This enables better control of the
power tool in unexpected situations.

6) Dress properly. Do not wear

loose clothing or jewelry. Keep
your hair, clothing and gloves
away from moving parts.

Loose clothes, jewelry or long hair

can be caught in moving parts.

7)

If devices are provided for the
connection of dust extraction and
collection facilities, ensure these
are connected and properly used.

Use of these devices can reduce

dust related hazards.

Power Tool Use and Care

1)

Do not force the power tool. Use
the correct power tool for your
application.

The correct power tool will do the

-

3 -

job better and safer at the rate for
which it was designed.

2)

Do not use the power tool if the
switch does not turn it on and off.

Any power tool that cannot be con-

trolled with the switch is dangerous
and must be repaired.

3)

Disconnect the plug from the pow­er source and/or the battery pack
from the power tool before making
any adjustments, changing acces­sories, or storing power tools.

Such preventive safety measures

reduce the risk of starting the pow­er tool accidentally.

4)

Store idle power tools out of the
reach of children and do not al­low persons unfamiliar with the
power tool or these instructions
to operate the power tool.

Power tools are dangerous in the

hands of untrained users.

5) Maintain power tools. Check for

misalignment or binding of mov­ing parts, breakage of parts and
any other condition that may af­fect the power tools operation. If
damaged, have the power tool re­paired before use.

Many accidents are caused by

poorly maintained power tools.

6)

Keep cutting tools sharp and clean.

Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.

7) Use the power tool, accessories

and tool bits etc. in accordance
with these instructions and in the
manner intended for the particu­lar type of power tool, taking into
account the working conditions
and the work to be performed.

Use of the power tool for operations
different from those intended could
result in a hazardous situation.

Battery Tool Use and Care

1)

Ensure the switch is in the off posi­tion before inserting battery pack.

Inserting battery pack into pow-

er tools that have the switch on in­vites accidents.

2) Recharge only with the charger

specified by the manufacturer.

A charger that is suitable for one type

of battery pack may create a risk of fire
when used with another battery pack.

3) Use power tools only with specif-

ically designated battery packs.

Use of any other battery packs may

create a risk of injury and fire.

4)

When battery pack is not in use,
keep it away from other metal ob­jects like paper clips, coins, keys,
nails, screws, or other small metal
objects that can make a connection
from one terminal to another.

Shorting the battery terminals to-

gether may cause burns, or a fire.

5) Under abusive conditions, liq-

uid may be ejected from battery;
avoid contact. If contact acciden­tally occurs, flush with water. If
liquid contacts eyes, additionally
seek medical help.

Liquid ejected from the battery may

cause irritation or burns.

Service

1) Have your power tool serviced by

a qualified repair person using
only identical replacement parts.

This will ensure that the safety of

power tool is maintained.

. SPECIFIC SAFE-

TY RULES

1) Wear ear protectors. Exposure to
noise can cause hearing loss.

2)

Use auxiliary handles supplied
with the tool. Loss of control can

cause personal injury .

3) Hold power tools by insulated grip-

ping sur faces when performing an
operation where the cutting tool
may contact hid den wiring.

Contact with a “live” wire will make

ex posed metal parts of the tool
“live” and shock the operator.

4)

Be aware that this tool is always in
an operating condition, since it does
not have to be plugged into an elec­trical outlet.

5) If the bit becomes jammed, imme­diately turn the trigger switch off
to prevent an overload which can
damage the battery pack or mo­tor. Use reverse motion to loosen
jammed bits.

-

4 -

6)

Do not operate the Forward/Reverse
lever when the trigger switch is on.
The battery will discharge rapidly
and damage to the unit may occur.

7) When storing or carrying the tool,
set the Forward/Reverse lever to
the center position (switch lock).

8) Do not strain the tool by holding
the speed control trigger halfway
(speed control mode) so that the
motor stops. The protection cir­cuit will activate and may prevent
speed control operation. If this hap­pens, release the speed control
trigger and squeeze again for nor­mal operation.

9) Be careful not to get dust inside the

chuck.

10) Do not touch the rotating parts to
avoid injury .

11)

Do not use the tool continuously for a
long period of time. Stop using the tool
from time to time to avoid temperature
rise and heat overload of the motor.

12) Do not drop the tool.

13)

Do not put the tool on the place where
the chuck cover is depressed. The bit
may come off from the chuck cover
and fall down when the chuck cover is
depressed. It may cause injuries.

. USAGE SUGGESTION

1. If there isn’t enough force pushing down on the bit, the hammer may not be able

to blow in hammering mode.

This is to prevent the hammering mode from operating with no load. Press down

harder on the bit to engage the hammer and cause it to blow.

Always be sure to press down with enough force when working.

2. In winter or in other situations where the temperature of the unit is low (5°C (41°F)
or below), the blow of the hammering mode may be weaker than normal at the be­ginning stage.

This is because the grease becomes stiffer in low temperatures, increasing fric-

tion.

If this should happen, operating hammering mode with no load for approximately

30 seconds and repeat this 3 times. This will restore its blowing power .
